<a name="index-introduction"></a>
<p>GNU Octave is a high-level language, primarily intended for numerical
computations. It is typically used for such problems as solving
linear and nonlinear equations, numerical linear algebra, statistical
analysis, and for performing other numerical experiments. It may also
be used as a batch-oriented language for automated data processing.
</p>
<p>Until recently GNU Octave provided a command-line interface with
graphical results displayed in separate windows. The current version
(version 3.8, released in late 2013) also provides, by default, a
graphical user interface.

<p>This manual provides comprehensive documentation on how to install,
run, use, and extend GNU Octave. Additional chapters describe how
to report bugs and help contribute code.
